. STORAGE BATTERY.

To allwhomtmay camera: Be it known that I, BRUcE FoRD, actzen of theUnited States, and a resident of Philadelphia, in the County ofPhiladelphia and .State of Pennsylvana, have nvented certain new anduseful Improvements in' Storage Batteries, of which the following is aspecification.

v The principal objects of the present 1nvention are, first, to improvethe Construction and operation of the means which'support the groups of'positive and negatve plates and their spacers or separators n properlyinsulated relation; second, to cushion the plates and parts againstshocls n cident to transportation thi-rd, to faclitate the use of glassjars in connection .with the separate supporting of positive andnegative groups of plates and their separators or spacers, and fourth,to enable the plate structure or assemblage and the supporting pedestaltherefor to be handled and inserted in and removed from the jar as aunitary structure. v

Other objects of the invention will appear from the followingdescription which will be given in connection with theaccompanyingdrawings forming part hereof and in which- Figure 1, is a perspectiveview of a plate I structure including the separators, and

'showing at the left a pedestal strip in its normal connected positionand .at the right a pedestal strip detached. e

Fig. 2,` is a longitudi'nal section of the lower part of a cell.

Fig. 3 is a transverse sectional view of the same, and

Fi 4, is a transverse sectional view showing portions of a pedestalstrip, a plate, and an insulator or spacer, and illustratin amodification of the invention.

n the'drawings, Figs. 1, 2 and 3,' 1 is a terials The strip 1, isadherent to the feet.

2, so that the plate structure or as'semblage can be ha dled' and`inserted into and removed from the jar 3, as a .unit. The ends of thepedestal strip may abut upon the sides of the jar .while the strip restsupon the bottom of the jar and for these reasons the pedestal strip iswell adapted for use in Specification of Letters atent.

connection with glass jars. The strips 1, are provided with sockets 4,for the reception of the plate feet or pins 2, and these sockets may beindividual, as shown, or continuous, like a trough as will' be readilyunderstood without further illustration. The strips are, or may be coredas indicated at 5, in order to lighten them and 'save material, while atthe same time increa'sing their elasticty. If of soft rubber the socketsand feet may be so proportioned as to cling to each other, otherwisethey may be made adherent by the use of pitch orthe like. 6 areseparators or spacers arranged between the plates 7, and they are shownlarger than the plates inorder to extend beyond the edges of the plates.Only the toes of the plate-feet or pns 2, may penetrate into the body ofthe pedestal stri s, and in that case the portion of 'the plate-feet orpins above the strips serves to hold the bottom edges of the platesabove the strips while the separators or spacers rest on top of thestrips and extend below the edges of the plates. -By` this ar- .platesand parts' against shocks such as.

occur in handling andtransportation. Each group of plates is connectedby a bus-bar 8, having a termi'nal9, and all the plates of a group canbe supported at one side by a pedestal strp, and at the other' side by a'terminal 9, sutably connected for that purpose with the cover of thejar.

The Construction and mode of'operation of the structure illustrated inFig. 4, are

the same as above described except that the socket or groove element P,is transferred from the pedestal strip to the foot or pin element Q andthe projecting element which coperates 'with the socket or grooveelement i 2 is formed on the pedestal strip.

. I claim:

1. In a storage battery' the .combination of a grou of' plates of likepolarity each havmg a oot, and a pedestal strip extending from plate toplate provided with a i i socket adherent to the 'feet of the plates,

whereby the group of plates` and the strip can be handled' as a ;untarfystructure.

2. In a 'storage battery the .combination of a group of plates 'of likepolarity each having a foot, and a pedestal strip provided withindividual sockets adherent to the feet,

whereby the plates and strip can be handled as a unitary` structure.

3. In a storage battery the combination of a jar, plates having feet andarranged in groups o like polarity, and pedestal strips extending acrossthe plates arranged on the bottom of the jar and each provided on itstop with a socket into which the feet 'of the plates of one groupproject. 4. In a storage battery the combination of a jar, plates havingfeet and 'arranged in groups of like polarity, and pedestal stripsabutting on the side walls of the jar and each provided on its top witha socket into which the feet of the platesof one group project.

5. In a storage battery the combination of a jar, plates having feetarranged in groups of like polarity, pedestal strips each provided onits top with a socket into which the toes of the feet of one group ofplates extend leaving the rest of the feet projecting abovethe top ofthe strips and spacing the bottom edges of the plates above the same,and Separator-s resting on the strips and extending below the bottomedges of the plates. 9*

6. In a storage battery the combination of a jar, strips resting on thebottom and side walls of the jar, positive plates having feet the endsof which penetrate certain of said strips, negative plates having feetthe ends of which penetrate the remaining strip, the portions of saidfeet above the strips holding the lower edges of the plates above thestrps. v

7. I n a storage battery the combination of an elastic pedestal strip,and a group of plates of like polarity having feet penetrating the bodyof the strip which. is adherent to the feet.

8. In a storage battery the combination of a soft rubber pedestal strip,and a group of plates of like polarity having feet pena trating the bodyof the strip which 's adherent to the feet. 9. In a storage battery thecombination of .soft rubber pedestal strips, a group of plates havingfeet penetrating the body of the strips and connected with it, bus-barsconnecting the plates, and separators between the plates and the stripsand the busbars, Whereby the parts constitute a u'nitary platestructure, substantially as described.

10. In a storage battery the combination of elastic pedestal strips, agroup of plates having feet penetrating the body of the strips andconnected with it, bus-bars connecting the plates, and separatorsbetween the plates and the strips and bus-bars, Whereby the partsconstitute a unitary plate structure, substantially as described.
